一、概述水涡轮减速机是炼厂延迟焦化装置无井架水力除焦的关键设备之一。近年来,国内几乎所有此类装置的炼厂都将水涡轮减速机更新为长岭炼油厂机械分厂生产的 CSC-Ⅱ型和 CSC-Ⅲ型水涡轮减速机(以下简称Ⅱ型和Ⅲ型),实现了设备长周期运转。以过去检修一次只能除焦1～14塔(T12M2-10减速机),发展到检修一次可以除焦209塔(CSC-Ⅲ型)。但是,由于各厂设备维修水平不一,也产生了一些问题,例如某厂一台Ⅲ型水涡轮减速机因事故停转了,拆开后却什么问题也没有发现,照原样装上后又能转了;又如某厂将二台事故停转的Ⅱ型水涡轮减速机,一
First, an overview Water turbine reducer is delayed refinery coking plant without derrick hydraulic decoking one of the key equipment. In recent years, almost all the refineries in China have updated the water turbine reducer to CSC-Ⅱ and CSC-Ⅲ water turbine reducer manufactured by Changling Refinery Machinery Factory (hereinafter referred to as type Ⅱ and type Ⅲ ), To achieve long-term operation of equipment. In the past overhaul only once coke 1 ~ 14 tower (T12M2-10 reducer), developed to overhaul can be a coke 209 tower (CSC-Ⅲ type). However, due to the different levels of equipment maintenance of various plants, some problems have also arisen. For example, a type III water turbine reducer in a certain factory has been stopped due to an accident. After disassembling, no problems have been found. Can turn; Another example is a plant will be two accidents stop Ⅱ type turbine reducer, one
